Iran does not have the legal right to nuclear weapons, because IRAN gave up that right upon joining the NPT. Iran can REGAIN that right if it resigns from the NPT, but so far Iran prefers not to. Moreover, Iran does NOT CLAIM the right to produce nuclear weapons. You are trying to be more pious than the Pope, which is not too productive, usually. Incidentally, Israel never joined the NPT. All this is very simple, but somehow you can't grasp it. My suggestion: See a doctor, schnell!
